220 Value of Native Gold, ce. 
Quantity of Quartz per Table, 8°68. 
This Gold-dust being fused into a button of Gold, and 
cleaned from the slag, weighed 955 grains, the difference 
between this and the original weight being 5°48 grains,— 
therefore the allowance in the Table is in excess. In this 
case it is possible’that the specific gravity of the matter in com- 
bination with the Gold was inferior to that of quartz, in which 
case it would require less to bring down the specific gravity 
to the point shown in the experiment.

These specimens being apparently clean, it would appear 
that there is something in the arrangement of the particles 
in a crystalline form which tends to diminish the specific 
gravity of the mass; or, what is perhaps more probable, that 
there is a central nucleus round which the particles of Gold 
have arranged themselves in a crystalline form.
